I think more harm brings noise than the heated air. Or electromagnetic learning, so I would not advise you to sleep in an embrace with a mining farm.
I have to say that I disagree, you
should embrace your gpus. There a high correlation between a gpu's overall level of happiness and productivity in terms of hashrate. Social needs are a factor to consider, and is beneficial for both you and your gpu.
Nothing puts me to sleep better than the hum of a hundred gpus.
I basically consider them part of the family at this point and you should too.
